Technological Advances Are Associated With Better Clinical Outcomes of Percutaneous Coronary Intervention in Patients With Unprotected Left Main Disease.
Article in Journal of the American Heart Association, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFew large-scale studies have evaluated the effectiveness of percutaneous coronary intervention (PCI) technological advances in the treatment of patients with unprotected left main coronary artery disease (LM-CAD). We aim to identify independent factors that affect the prognosis of PCI in patients with unprotected LM-CAD and to assess the impact of PCI technological advances on long-term clinical outcomes. METHODS AND
resultsA total of 4512 consecutive patients who underwent unprotected LM-CAD PCI at Fuwai Hospital from 2004 to 2016 were enrolled. Multivariable Cox proportional hazards model was used to identify which techniques can independently affect the incidence of major adverse cardiac events (MACEs; a composite of cardiac death, myocardial infarction, or target vessel revascularization). The incidence of 3-year MACEs was 9.0% (406/4512). Four new PCI techniques were identified as the independent protective factors of MACEs, including second-generation drug-eluting stents (hazard ratio [HR], 0.61 [95% CI, 0.37-0.99]), postdilatation (HR, 0.75 [95% CI, 0.59-0.94]), final kissing balloon inflation (HR, 0.78 [95% CI, 0.62-0.99]), and using intravascular ultrasound (HR, 0.78 [95% CI, 0.63-0.97]). The relative hazard of 3-year MACEs was reduced by ≈50% with use of all 4 techniques compared with no technique use (HR, 0.53 [95% CI, 0.32-0.87]).
conclusionsPCI technological advances including postdilatation, second-generation drug-eluting stent, final kissing balloon inflation, and intravascular ultrasound guidance were associated with improved clinical outcomes in patients who underwent unprotected LM-CAD PCI.
